Present field experiment was conducted during Rabi seasons of 2016-17 at research farm of BAU, Sabour to study the screening of the best genotype of garlic for yield and yield attributing traits against Stemphylium Blight in Agro-climatic zone IIIA of Bihar. Garlic (Allium sativum L.) is considered as one of the most important species in the family Alliaceae and as an important bulb crop next to onion. It is attacked by a number of diseases of which, in field condition, stemphylium blight is the most economically important diseases. The results revealed that, the maximum plant height ( cm) was recorded in genotype BRG-13 and lowest ( cm) in RG-463. The maximum number of leaves per plant was observed in WG-73 () and minimum in BRG-3 (). The maximum length was recorded in genotype 507 ( cm) and minimum length ( cm) of leaf was found in genotype 569. The maximum breadth of leaf was obtained in genotype BRG-10 ( cm) and minimum in the genotype 507 ( cm). Genotype 644 had thick neck () and less thicker neck was obtained in genotype G 323 ( cm). The minimum was recorded with the genotype IC 375005 ( cm) and maximum polar diameter of bulb with genotype WG-73 ( cm). | Screening of garlic genotypes for yield and yield attributing traits against stemphylium blight
